GLASS-GATHERING MACHINE.

Specification of Letters Patent.

Patented Dec. 18, 1906.

Application filed November '7, 1905. Serial No. 286,270.

To all whom it may concern.-

Be it known that 1, Ross D. BROWN, a citizen of the United States, residing at Muncie, in the county of Delaware and State of Indiana, have invented a new and useful Glass- Gathering Machine, of which the following is a specification.

The invention relates to improvements in glass-gathering machines.

The object of the present invention is to improve the construction of glass-gathering machines and to provide a simple and comparatively inexpensive one adapted to move a rotating gathering instrument into a tank and capable after the gathering instrument has been extended into the tank of dropping it to the surface of the glass to permit it to gather its quota and of then raising the instrument substantially in a vertical direction, so as to cut off the thread of the glass.

A further object of the invention is to provide a machine of this character adapted after the gathering instrument has gathered its quota of glass of withdrawing the same from the tank and of swinging it backward in a straight vertical plane to the rear of the machine over a mold and of stopping the rotation of the gathering instrument at the limit of such backward movement to cause the glass to drop into the mold.

The invention also has for its object to dispense with the carriage or frame heretofore employed for moving the gathering instrument to and from the glass and to enable the gathering instrument to be directly actuated both in introducing it into and removing it from the tank and swinging it to and from the mold.

Furthermore, the invention has for its obj ect to provide simple means for controlling the downward movement of the gathering instrument within the tank and for increasing such movement as the glass is consumed, whereby the machine will properly gather thelglass at any level of the latter within the tan r.

With these and other objects in view the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in'the accompanying drawings, and pointed out in the claims hereto appended, it being understood that various changes in the form, proportion, size, and minor details of construction within the scope of the claims maybe resorted to without departing from the spirit or sacrificing any of the advantages of the invention. 3

In the drawings, Figure 1 is a plan view of a glass-gathering machine constructed in ac- 6o cordance with this invention. Fig. 2 is a vertical longitudinal sectional view on the line 2 2 of Fig. 1. Fig. 3 is a transverse sectional view on the line 3 3 of Fig. 2. Fig. 4 is a perspective view illustrating the arrangement of the cams and weighted levers for actuating the gathering instrument. Fig. 5 is a detail sectional view illustrating the construction of the extensible gathering instrument. Fig. 6 is a horizontal sectional view on the line 6 6 of Fig. 3. Fig. 7 is a detail sectional view on the line 7 7 of Fig. 5.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

1 designates an extensible gathering instrument consisting of inner and outer telescopic sections or members, the inner section 2 being tubular and slidably receiving the inner portion 3 of the outer section, which terminates in a head or enlargement for gathering glass. The inner end 4 of the gathering instrument is bifurcated and is pivoted by a pin 5 or other suitable fastening device to a vertically-movable rod 6, which is adapted to be moved upward and downward, as hereinafter more fully described, to raise and lower'the outer end of the gathering instrument The inner portion 8 of the outer section of the gathering o instrument is reduced at opposite sides to form flat faces and to provide a non-circular portion for engaging a pinion 7, which is therebyslidably connected with the gathering instrument. The other edges of the por- 5 tion 3 of the outer section are rounded to enable the outer section to rotate freely within the inner tubular section 2, which forms a bearing for the outer section. The opening of the pinion, which conforms generally to I00 the configuration of the portion 3 of the gathering-iron, is slightly larger than the same to permit the necessary play of the parts; but instead of slidably connecting the pinion and the gathering-iron in the man nor shown any other suitable means, such as a key and keyway, may be employed for this 1 purpose.

The pinion, which imparts a rotary movement to the gathering-iron, meshes with a large vertically-disposed gear 8, and it forms a fulcrum and guide for the gathering instrument while the same is being introduced into and removed from the tank. The gathering instrument is extended by the means hereinafter described to introduce it into the tank, and it is tilted or oscillated on the pinion to raise and lower the point of the gathering instrument, which movement is substantially vertical and is effected after the instrument has been extended into the tank. The rotary movement enables the gathering instrument to pick up its quota of glass and retain the same on it, as will be readily understood, and. the large gear 8, which is disposed transversely of the front of the machine, is mounted on a horizontal shaft 9, disposed longitudinally of the machine and journaled in suitable bearings of the frame thereof. The longitudinal shaft .9 is provided in rear of the large gear 8 with a pinion 10, which is driven by a gear 11 of I fulcrumed at one end 31 on the frame, prefer' a main transverse shaft 12, also journaled in' suitable bearings of the frame of the machine and carrying the cams, hereinafter described, for effecting the several movements of the gathering instrument. The frame of the machine may be constructed in any pre ferred manner, and it preferably consists of a horizontal top portion 13 and supporting corner-standards 1 1, which are suitably connected and braced to afford the requisite strength,

The main transverse shaft, which may be driven by any suitable means, is preferably provided with a gear 15, meshing with a pinion 16 of a short counter-shaft 17, which car ries a pulley 18, adapted to be connected by a belt with a suitable driving-pulley. A clutch 19 and a shifting-lever 20 are provided for throwing the machine into and out of operation. The shifting-lever is fulcrumed on an arm 21, extending from the frame of the machine, as clearly illustrated in Fig. 1 of the drawings; but the lever may be arranged in any other 'desired manner, as will be readily understood.

In order to move the gathering instrument into and out of the tank, a lower transverse rock-shaft 22 is employed. This rockshaft, which is journaled in suitable bearings of the frame of the machine, is provided with an upwardly-extending arm 23, having a forked upper portion 24 to receive the gathering instrument. The sides of the fork 24 are provided with slots or openings 25, through which the outer section or member of the gathering instrument extends, the said outer section being provided with an adj ust able collar 26, arranged within the fork between the sides thereof and secured to the gathering instrument by means of a setscrew 27. By adjusting the collarfon the outer section or member of the gathering instrument the latter is positioned properly with relation to the movement of the forked arm of the rock-shaft 22. This adjustment of the gathering instrument enables it to extend the desired distance into the tank from which the glass is to be gathered. WVhen therock-shaft is actuated, the upwardly-extending arm 23 is oscillated and the outer section or member of the gathering instrument is moved longitudinally through the pinion 7 and into and out of the tubular inner section or member 2. The slots or openings 25 extend downward from the upper ends of the sides of the fork to provide an open bearing or seat for the gathering instrument to permit the same to be swung from the forked arm 23 and the seat thereof, as hereinafter explained.

The rock-shaft 22 is provided with an inwardly-extending arm 28, disposed in an approximately horizontal position and connected by an upwardly-extending link 29 with a weighted lever 30. The weighted lever 30 is ably by means of a depending arm 32 of a bracket 33, and its other end is provided with an adjustable weight 34, adapted to be moved inward and outward to vary the downward pressure of the lever. The weight 34 may be adjusted on the lever by any suitable meanssuch as a bolt 35 and perfora tions 36, formed in the lever 30to permit the bolt to be arranged at different points on the the same. The weighted lever 30, which op.- erates in a suitable guide 30, is provided with an antifriction-wheel 37, which rests upon a cam 38 and which is mounted in an opening 39 of the lever 30. The cam 38, which is mounted on the main transverse shaft 12, is adapted to positively swing the lever 30 upward, and it permits the same to swing downward to rock the shaft 22 and move the extensible gathering instrument outward and inward to advance it into the tank and to withdraw it therefrom. The machine is properly timed, so that the gath ering instrument will be first advanced into the tank the proper distance and then moved directly downward to the surface of the glass to avoid a skimming movement along the surface of the glass, and thereby avoid abruptly breaking the glass when the gathering instrument is lifted therefrom. The upward movement of the gathering instrument from the glass will be in substantially a vertical direction and not backward or forward over the surface of the glass, and the glass will not be suddenly broken by the Withdrawal of the gathering instrument, as is the case with ma, chines employing a skimming movement during the gathering operation.

The upward. and downward movement. of

the outer end of the gathering instrument is effected by means of a transversely-disposed oscillatory lever 40, fulcrumed at an interme diate point in a bracket 41 and provided at its inner end with a head 43, which has a forked flange 44, straddling the verticallymovable rod 6 and forming a seat for an adjustable collar 45. The collar 45 is secured in its adjustment by a set-screw 46, and it enables the rod 6 and the gathering instrument to be adjusted independently of the lever 40. The lever 40 is provided at an intermediate point with an adjustable sleeve 47, secured to the lever by a set-screw 48 and provided with opposite pivots or trunnions 49, which are arranged in suitable bearings of the bracket 41. The bracket 41, which is suitably secured to the top of the frame of the machine, is provided with vertical sides spaced apart to receive the lever 40. The outer end 50 of the lever is slotted or bifurcated to receive a link 51, which is forked at its lower end 52 and which is pivoted to an arched bar or piece 53 of a weighted lever 54. The upper portion of the link 51 is provided at intervals with perforations 55, and the outer end of the lever is adjustably secured to the link by means of a pin 56, adapted to be placed in any one of the perforations 55. The lever 54 is fulcrumed at one end on a depending arm 57 of the said bracket 33, and it is provided between its ends with an opening 58, in which is mounted an antifrictionwheel 59, over which the arched bar or piece 53 extends. The other end of the lever 54 operates in a guide 54 and is provided with an adjustable weight 60, preferably constructed and arranged similar to the weight 34 of the lever 30. The antifriction-wheel 59 rests upon a cam 61, which is also mounted on the shaft 12 and which is arranged to drop the outer arm of the lever 40 at the completion of the outward movement of the extensible gathering instrument. This downward movement of the outer arm of the lever 40 lifts the inner end of the gathering instrument and moves the outer or gathering end of the same downward to the surface of the glass.

The cams are adjustably mounted on the shaft 12 and are preferably braced by connecting-bolts 62, extending across the space between the cams 38 and 61 and piercing the same, as clearly illustrated in Fig. 3 of the drawings. After the gathering instrument has gathered its quota of glass it is lifted from the glass of the tank by the cam 61, which raises the weighted lever 54, thereby swinging the outer arm of the transverse lever 40 upward. This permits the inner end of the gathering instrument to descend, the weight of the vertically-movable rod 6being sufficient to insure a downward movement of tively moved downward by the lever 40, as will be readily understood. This can be effected by arranging an adjustable collar beneath the fork 44 in addition to the collar above the same. As this is obvious, illustration thereof is deemed unnecessary. At the completion of the upward movement of the outer end of the gathering instrument the latter is withdrawn from the tank by a backward movement of the forked arm 23, which backward movement is effected by a downward movement of the weighted lever 30 due to the rotary movement of the cam 38.

After the gathering instrument is withdrawn from the tank it is swung backward over the top of the machine in a vertical plane from the position illustrated in full lines in Fig. 1 to that shown in dotted lines to deposit the glass in a mold. During this oscillatory movement of the gathering instrument it is counterbalanced by a weighted. arm 63 of a vibratory shaft 64, disposed transversely of the machine and journaled in suitable bearings of a bracket 65 and provided with an arm 66, which is connected with and which loosely receives the gathering instrument. The arm 63, which is arranged at the outer end of the vibratory shaft 64, is provided at its outer portion with perforations 67, adapted to receive a fastening device 68, which also pierces a weight 69. The weight 69 is adapted to be adjusted inward and outward on the arm 63 to properly counterbalance the weight of the gathering instrument. The bracket 65, which is suitably mounted on the frame of the machine,

,is provided with upwardly-extending arms having bearing-openings to receive the shaft 64. The arm 66, which is arranged at the inner end of the shaft 64, is provided with a laterally-extending flange or portion 70, having an opening, which'loosely receives the inner tubular member 2 of the gathering instrument. The arm 66 is also provided'with a slotted guide, which receives the pinion 7 and which maintains the same in proper position'to mesh with thegear-wheeiltS when the gathering instrument is swungf orward. from the back of the machine to the, front thereof. This slotted guide is composed of two laterally-projecting flanges '71, having slots or openings 72 extending upward from the lower ends of the flanges 71 and receiving the portion 3 of the gathering instrument, which has a limited play on the arm 66.

The vibratory shaft is provided with a mutilated pinion 73, which meshes with an oscillatory toothed segment 74 of a lever 75. The lever 75, which is fulcrumed between its ends on an upwardly-extending arm of a bracket 76, has its outer or rear arm con nected by a link 77 with a weighted lever 7 8. disposed longitudinally of the machine in the inner end of the gathering instrument. l parallelism with the weighted levers 30 and The lever 78, which is adjustably ful- The vertically-movable rod 6 may be posi- 1 54.

'crumed at its front end on the depending mounted onthe main transverse shaft, and

it is adapted to move the weighted lever 78 upward, and thereby oscillate the lever 75, which carries'thetoothed segment 74. The upwardmovement of the weighted lever 78 moves the toothed segment 74 downward .androtates the shaft 64 to swing the gathering instrument from the front of the inachine to the back thereof.

The gatheringinstrument isrotated during its oscillatory stroke or movement to retain the glass on it by means of a curved rack 84, provided with teeth arranged to mesh with the pinion 7. The curved rack is mounted on an arch 85, extending from the front to the back of the machine and supported by suitable braces 86. The toothed rack, which positively rotates the gathering instrument, terminates short of the rear end of the arch, so that the rotation of the gathering instrument will cease at the limit of its backward movement to permit the glass to drop into the mold, the glass being cut off from the gathering instrument by the attendant. The arch carries front and rear guards 87 and 88, having laterally-extending guiding portions and provided with shanks which are secured to the arched bar 84. These guards limitthe outward movement of the outer section of the extensible gathering instrument and guide the adjustable collar to the seat formed by the fork of the arm23 and also to prevent any outward movement of the gathering instrument from carrying the glass beyond the mold. The gathering instrument. is positively swung backward by the action of the cam 82, and in order to prevent any undue jar of the parts when the gatheringinstrument is swung forward by the weight 83, a cushion or buffer 89 is provided. This cushion or buffer 89, which is arranged to be engaged by the laterallyextending flange 70, consists of a bowed spring presenting an upper convex face to the flange and secured at one end to the top of the frame. The other end (f the bufler or cushion is free to permit the spring to yield. to and cushion the gathering instrument.

It will be seen that the extensible gathering instrument is adapted to dispense with the carriage or frame usually employed for moving a gathering instrument into and out of a-tank and that the downward movement to drawn by such movement.

I dip the gathering instrument into the glass occurs at the end of the inward movement, and thereby prevents a skimming movement on the surface of the glass and the consequent sudden breakage of the thread of the" glass when a gathering instrument is with- Also it will be clear that the machine is readily adjustable to cause the gathering instrument to dip into the tank the desired distance and that the dippingmovement may be increased as the glass within the tank is consumed. Furthermore, it will be clear thatthe extensible gathering instrument may be readily adjusted to extend into the tankthe desired distance and that as the gathering instrument in swinging from the tank tothe mold does not have any'lateral movement a number of machines maybe placed closely around a tank or pot.
